Clean area thoroughly with soap and water solution and wipe completely dry. Use alcohol pad to prep the tape application area and let dry. Wait until after Tailgate Seal is installed before applying very firm pressure, to secure adhesive bond. If necessary, Tailgate Seal can be removed and repositioned prior to applying very firm pressure. Pictures shown below are for the left sidewall and tailgate gap.

Start 1” below truck bed floor and attach seal to the rear corner edge of the left sidewall extension (FIG 1A). When nearing top of sidewall, gradually rotate seal 90° counter clockwise so that bulb is facing inward and the taped side of seal is flush with the sidewall at the top (FIG 1B). Apply light pressure to adhesive. Duplicate for the right sidewall.
Cut and attach a 3" piece just below the top of bedrail. Flush to the seal on the sidewall extension, bulb side facing outwards. Apply light pressure to adhesive. Duplicate for the right sidewall.

Start at either end of the tailgate gap and flush with Tailgate Seal on the sidewall. For this application the hinges, near the sidewalls, make the width of the tailgate gap smaller for the first 4" to 5". Simply invert seal so that bulb side is down. Cut a piece and attach, apply light pressure to adhesive. Duplicate for the right side of tailgate gap.

Continue attaching seal, bulb side up, to the tailgate gap. Align seal just below the lower ridge of truck bed floor. Peel back liner and attach in sections, applying light pressure to adhesive. When flush with inverted seal on the right side cut to fit.

Cut and attach a 3.750" piece to the side of tailgate, near the top, bulb side facing left. Cut and attach a .750" piece and position as shown in picture. Apply only light pressure to adhesive. Duplicate for the right side.

Alternate View
Close tailgate. If you see light through the sidewalls, make adjustments by removing the seal and repositioning. If there is still light then cut pieces of seal, as needed and attach to sidewalls and/or tailgate. Do not attach adhesive to seal. After Tailgate Seal is in place, apply very firm pressure to secure the adhesive bond.
